getMgmtDisc error

[chunhujeon]

I encountered an issue using getMgmtDisc. Specifically, when there is missing 10-K in the year, it returns
Error in XML::free(doc) : object 'doc' not found
and terminates its function without moving to the next document.

I guess there is an issue in line 177 but I am not sure whether it is.
rm(f.text); XML::free(doc)

It happened to me too, the filling is downloaded in the directory of the project, no problem with that, however the error happens with filings starting in 2019 and the only difference with previous years is that the format changed to the new iXBRL format.
